Comment # 14 on bug 74250 from Luzipher

Fixed: the error messages are gone with the following commits on branch
'drm-next-3.17-wip':
* drm/radeon/dpm: handle voltage info fetching on hawaii
* drm/radeon/atom: add new voltage fetch function for hawaii

Dynamic mclk is not supported with multiple monitors according to agd5f on irc.

@Kai: since you apparently tested with the now useless patch from attachment
#93015 [details] [review] last time, maybe you want to try with current unmodified
'drm-next-3.17-wip' again ? (Don't forget the updated firmware, I always do ;-)
). If that still doesn't resolve your issues, please open a new bug.
